Just an article I came across in my wanderings as related to mental illness and marriage that I thought might appeal to some since the issue came up in this topic:
NAMI: Beating the Marriage Odds
Readers should be aware that the initial paragraphs can be somewhat discouraging -- if you're feeling triggery, right now might not be the best time to read it. However the article does get better as you read further, particularly at the point that marriage partners begin to offer some specific examples of how they have successfully coped with the difficulties that bipolar disorder can bring to an intimate partnership.
